Intensively managed landscapes represent anthropogenically-modified systems, actively managed for industrial scale agricultural production. These modifications reflect changing land use and land management practices over time, intensification of mechanized practices, use of fertilizers and other chemicals, draining of wetlands, and in many cases adoption of best management practices to reduce environmental impacts. These modifications impact the dynamics of water, carbon, nitrogen, and sediment in the landscape in complex ways not yet well understood. Given the increasing demand for food and biofuel and concerns about adverse effects of agricultural intensification, process-level understanding of these landscapes for predictive modeling and scenario testing is imperative. This special section invites contributions that enhance our understanding of such intensively managed systems at the field to watershed to regional scales and from observations, to modeling, to prediction, to policy and management.
